IWMReaderPlaylistBurn::Cancel method (wmsdkidl.h)

[The feature associated with this page, Windows Media Format 11 SDK, is a legacy feature. It has been superseded by Source Reader and Sink Writer. Source Reader and Sink Writer have been optimized for Windows 10 and Windows 11. Microsoft strongly recommends that new code use Source Reader and Sink Writer instead of Windows Media Format 11 SDK, when possible. Microsoft suggests that existing code that uses the legacy APIs be rewritten to use the new APIs if possible.]

The Cancel method cancels an initiated playlist burn before initialization is finished.

Syntax

HRESULT Cancel();

Return value

The method returns an HRESULT. Possible values include, but are not limited to, those in the following table.

Remarks

You should call this method to cancel the playlist burn process only after calling InitPlaylistBurn and before your status callback receives the WMT_INIT_PLAYLIST_BURN message. If you need to cancel the playlist burn after initialization is finished, you should call the EndPlaylistBurn method and pass the E_ABORT error code.
